rly need help
You can use this page to see roughly which “tier” a server is in.
The top end has much higher WvW populations, especially during off hours (i.e. outside of Western-Europe evening for EU servers or outside of NA evening for US servers), and some kind of organized thing going 24/7. They’ll also tend to have queues during peak hours.
The lower you go, the more sparsely-populated stuff gets, especially during off hours. Past that you sorta need to inquire about individual servers/matchups because exactly why Server X is in a particular spot can vary dramatically. You might find a tier-3 server that has a great and balanced OCX matchup but loses the entire map on SEA, for example. I don’t know much about the EU servers so I can’t say anything more specific.
thx for replay =) that page link rly help=)
Note that the top-end servers tend to be “full” a lot so transferring to them requires waiting a bit. Best way to do it is to contact someone (they’re often recruiting WvWers) and ask them.
